8 Claims.

' latter is inserted in the dispenser, the liquid contents quickly owing into the dispenser from the receptacle through the opening in the cut wall while the receptacle is held in the cutting el'ement in an emptying position.

An object of the present invention is the provision of a single cutting element which is held in xed position on an inside wall of a liquid dispenser, this element cutting into an end wall of a liquid containing receptacle when the latter is moved downward over the cutter, the liquid contents then quickly draining into the dispenser through the cut opening which is at a low drainage point of the receptacle as the liquid is being dispensed from the dispenser.

The invention also contemplates the use of a cutter of simple construction which combines .in one single cutting element an easily insertable receptacle wall cutter which not only elects an opening for the discharge of the liquid in the receptacle with a simple single movement but at the same time lays back the metal of the cut wall and also vents the receptacle to produce a rapid draining.

Numerous other objectsv and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawing, discloses a preferred embodiment thereof.

Referring to the drawing:

Figure 1 is a side elevation of a liquid dispenser embodying the present invention; parts being broken away and parts being shown in section; the view also showing a sealed receptacle just above the open end of the dispenser and in position for insertion therein;

Fig. 2 is a similar View, the upper part of the liquid dispenser showing a sealed receptacle in liquid discharging position fully inserted and supported within the dispenser;

Fig. 3 is a plan sectional view partly broken away taken substantially along the line 3--3 in Fig. 2; and

Fig. i is an enlarged front elevation in detail of the cutter detached from the dispenser.

The drawing illustrates a preferred embodiment oi the invention as it is adapted to dispensing lubricating oil such as is used in automobiles and in such embodiment there are broadly three main elements, a dispenser A, a cutter B and a sealed oil container receptacle C.

The dispenser A is similar to dispensers vnow commonly used in oil and gasoline stations and in garages for dispensing lubricating oil into auto- 5 lmobile crank cases and the like and is adapted to its instant use by those necessary changes which will be fully pointed out in the description that follows. It comprises a cylindrical -body II open at the top and having an upper outwardly curled j10 or rolled edge or bead `I2 and a similar lower rolled edge or bead I3.

A bottom I4 is secured within the body II and is preferably depressed at I5 to form a discharge wall which directs the oil into a discharge pipe i5 I6 connected by means of a -flexible hose or tube Il to a discharge spout I8. When the receptacle is in non-discharging position the spout I 8-is adapted to be engaged and supported in the position illustrated in. Figs. 1 and 3 by a hook I9 se- 20 cured toand extending horizontally from the upper bead I2 of the body II. A handle 2| is connected by an upper strap 22 and a lower strap 23 to the outside wall of the body I I directly opposite to the hose and spout Il, I8. 25

A cutter B for opening the receptacle C is secured in the upper part of the body II of the dispenser A and is formed like the letter U with a curved body wall 25 (Figs. 1, 3 and 4) bent back on both sides at sharp angles into straight 30 side walls 26. These walls 26 are secured by rivets 21 to legs 28 of a U-shaped supporting strap 29. The end of each leg 28 is bent outwardly intol a foot or lug 3| and the two lugs are held rigidly against the inside wall of the 35 body II by screws 32. I

'I'he cutter body 25 near its upper end is formed into a curved cutting wall 35 the curve of which is larger than the curve of the wall 25 and` smaller than the curve or' the inside wall of the dis- 40 penser. These curved surfaces are all concentric and the cutting wall 35 is spaced inwardly from the adjacent inner dispenser wall when the cutter is in its held position within the dispenser. This cutting wall is spear shaped along its up- 45 per edge coming to a center-point 36 (Fig. 4).

It is also beveled at 3l to provide a sharp cutting edge. The beveled edges extend along the tops of the side walls 26. The U-strap 2s is further supported by a hori- 50 zontal extensionl 38 which extends from the bottom edge of the center part of the strap, terminating in a foot 39. which'is secured by a screw II to the wall of the body I I. The rigid mounting of the cuttery B inside the dispenser A greatly facilitates its opening action as the filled receptacle C is introduced into the open upper end of the dispenser and pushed down on the cutter as will now be described.

Downward movement of the receptacle C within the dispenser impales its bottom wall 45 (Fig. 2) rst on the cutter point 36 and thence the wall moves downwardly over the tapered cutting edges 31 and over the side walls 26. At the same time the bottom wall 45 strikes against and its cut portion is bent by a curved upper end 46 (Figs. 1 and 4) of a deflecting bar 41 preferably formed as an integral part of the strap 29 and extending upwardly at an angle from the upper edge of the strap.

The nal position of the receptacle C within the dispenser A is illustrated in Fig. 2 where its bottom edge or rim rests upon the upper edge of the strap 29. The severed part of the wall 45 of the inserted receptacle C (designated by the numeral 48, Figs. 2 and 3) is now bentv back over the inclined wall of the deflecting bar 41 and in cross section is curved as shown in Fig. 2. It is out of the way of the liquid iiowing through the discharge opening. This discharge opening is obviously outlined on three sides by the lines of severance cut through the receptacle wall by the cutter. The cut edge adjacent the dispenser wall is substantially at the inside wall of the receptacle so that there is no bottom ledges of the receptacle bottom wall on that side to impede the flow of liquid through the opening.

In .order to assist in rapid discharge of the liquid from the receptacle C, air is directed through the cutter and into the interior of the receptacle to replace the discharging liquid. The cutter wall 25 is perforated at 49 and air surrounding the receptacle C is led through the openings 49 (see Fig. 2) through the liquid in` the receptacle and into the space above. Such air together with possible entralned air passing in through the discharge opening of the receptacle wall assists in a rapid and e'icient flow of the oil from the receptacle into the dispenser.

The capacity of the dispenser A is such as to hold the entire contents of the liquid passing from the receptacle C without the nal liquid level in the dispenser coming up to the bottom of the receptacle C. This receptacle, which in the embodiment shown, projects above the open end of the dispenser and is held in place with. its opened bottom wall clinging to the cutter, this holding action being sufficient to prevent dis- `)lacement while the oil is discharged through the iiexible hose l1 and the pouring spout in the usual manner.

For the dispensing action the dispenser A is heldA by thelhandle 2| and the natural position of the dispenser at such time is slightly tilted so that the opening cut inthe bottom wall of the receptacle by the cutter B is at the lowest position.y 'I'his gives full draining time and insures removal of all of the contents of the receptacle C.

With a single downward pressure upon the receptacle C as it is inserted into the dispenser A sufficientof the engaged receptacle wall 45 is cut out to provide an adequate discharge opening from which the contained liquid cascades into the dispenser. 'Ihe turned back wall 48, being en tirely out of 'the way, oiers no restriction to the flow of oil through the opening and the air rushing in through the discharge opening and being partly guided through the openings 49 in the cutter prevents any blocking of the iiow because of inadequate venting. 'These openings 49 also assist in draining all of the oil fromthe cutter B after the receptacle C has been emptied.

It is thought that the invention and many of its attendant advantages will be understood 5 from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts Without departing from the spirit and scope of the invention or sacricing all of its material ad- 10 vantages, the form hereinbefore described being merely a preferred embodiment thereof.
